MODE OF COUPLING FOUR-WHEELED CARRIAGES.

Specification of Letters Patent No. 2,932, dated January 27, 1843.

To all whom, it may concern:

Be it known that I, ALFRED Oscoon, of Charlestown, in the county ofPortage and State of Ohio, have invented a new and Improved Mode ofCoupling for Four-Wheeled Carriages, Wagons, or Vehicles; and I dohereby declare that the following is a full and exact description.

The nature of my invention consists in providing the forward aXletree ofa carriage, wagon, or vehicle with a double rotary coupling joint, asrepresented in Figure 1, letter A, the design of which is to givesafety, freedom, and ease to the horizontal and vertical motion of theforward axletree of such Vehicle.

To enable others skilled in the art, to make and use my invention, Iwill proceed to describe its construction and operation.

I construct my carriages or wagons in any of the known forms and providetwo circu lar plates of iron, or other suitable material, (see Figs. 2and 3). One of which (Fig. 2) is fastened to the lower side of the reachand head block of the carriage or wagon. In the center of this upperplate, is a hole (Fig. 2 letter 0) of suflicient size to admit a gudgeon(Fig. 3, letter e) which projects from the center of the lower plate,and is of sutficient size and strength to hold the whole The two platesare confined together by two hooks, one of which projects downward fromthe forward edge of the upper plate (Figs. 2 and 4, letter (Z) andshutting over the edge of the lower plate. The other hook. (Fig. 4,letter f) is fastened to the reach and shuts over the hinder edge of thelower plate, thus confining them close together, and yet permitting themto play easily upon each other, on the central gudgeon projecting fromthe upper surface of the lower plate, thus securing to the forwardaXletree, an easy horizontal motion. The lower plate rests upon the for7 or flanges is hollowed out and forms a part of a circle (Fig. 4,letter h) and rests upon a piece of metal which is bolted to theaxletree (Fig. 5, letter the upper surface of which is cylindrical andfits the hollow surface in the lower plate. A pin or bolt (Fig. 3,letter passes through the wings and aXletree, at a point which willdescribe the circle in the lower plate, and in this manner secure thejoints from rising up. By this operation the aXletree has a freeVertical motion.

WVhat I claim as my invention and desire to secure by Letters Patent, is

Attaching the axle-tree to the lower rotating plate by a joint pin inthe manner described, so that the front axle-tree can swivelhorizontally and vertically, independent of the back axletree.
